What does support force do in physics?
A support force in physics is a reaction force that acts to prevent an object from falling through a surface. It is typically exerted by a solid surface such as the ground or a table in response to the weight of an object resting on it. This force is equal in magnitude but opposite in direction to the force of gravity acting on the object.
When a falling object hits the ground does the ground apply an upward force?
Yes, according to Newton's third law of motion, for every action, there is an equal and opposite reaction. When a falling object hits the ground, the ground applies an upward force on the object, resulting in the object coming to a stop.
When a falling object stops it has reached what?
Typically the ground.
Give examples for non uniform motion?
A falling object, if there is no significant air resistance, will fall faster and faster before it hits the ground. Similarly, a satellite in orbit around the Earth changes its direction, and therefore its velocity, all the time. (In physics, "velocity" describes a speed at a certain direction.)
What describes free fall?
When only gravity acts on a falling object.
What happens the the kinetic energy of a falling object?
As a falling object descends, its potential energy (due to its position above the ground) is converted into kinetic energy (energy of motion). This kinetic energy increases as the object accelerates towards the ground. When the object reaches the ground, all of its potential energy is converted into kinetic energy.
Why doesn't a falling object continue falling forever?
It does continue falling, until it runs into something that stops it, like the ground.
What is the concept of momentum in physics?
In physics, momentum is a measure of an object's motion, determined by its mass and velocity. It describes how difficult it is to stop an object in motion and is conserved in a closed system.
What is the effect of gravity on a falling object?
Gravity causes a falling object to accelerate towards the ground at a rate of approximately 9.8 m/s^2 (on Earth). This acceleration due to gravity increases the speed of the object as it falls towards the ground.
What is the kinetic energy of the free falling object that eventually stop on reaching the ground?
Once the object has reached the ground, its kinetic energy is zero.
What term describes an object that is falling and the only force acting on it is gravity?
Free fall describes an object that is falling and the only force acting on it is gravity. In free fall, the object is accelerating downward due to the force of gravity without any other forces affecting its motion.
What is the meaning of p in physics?
nothing really it is just how they spell it
